A/C Relay | Special Functions/ Output Controls |
Important: The A/C Relay Command parameter may not change states when using this output control. This function activates the A/C compressor relay. The normal commanded state of the A/C relay is OFF. The A/C compressor will turn ON/OFF when commanded ON/OFF. The system remains in the commanded state for approximately 5 seconds. The engine control module (ECM) will inhibit the operation of the A/C relay when the ambient air temperature is low. | ||||||||
